WVILLIAM HUGERSHOFF, OF BROOKLYN, NElV YORK..-

ATOMlZER-NOZZLE.

SPECIFICATION forming part Of Letters Patent NO. 402,831, dated. May 7, 1889. Application filed December 8, 1888. Serial No. 292,981. (No model.)

To all whom, it may concern.-

Be it known that I, WILLIAM HUGERSHOFF, of Brooklyn, in the county of Kings and State of New York, a citizen of the United States, have invented certain new and usefullniprovements in Nozzles for Atomizers, of which the following is a specification.

This invention relates to 'an improved nozzle for atomizers, whereby a more uniform action of the spray-nozzle is produced, and a uniform and continuous spray is produced by the same without any irregular intermittent jet action; and the invention consists of a nozzle for atomizers, said nozzle being detachably inserted into the air-supply tube connected with an air-forcing bulb, and a section-tube leading from the nozzle into the vessel containing the liquid to be atomized, said nozzle being provided with a central channel communicating with the suction-tube and with one or more laterally-inclined airchannels which meet in the central channel and which communicate with the air-space around the suction-tube, as will be fully described hereinafter, and finally pointed out in the claim.

In the accompanying drawings, Figure 1 represents a perspective view of an atomizer with my improved nozzle, and Fig. 2 is a vertical longitudinal section of the nozzle drawn on a larger scale.

Similar letters of reference indicate corresponding parts.

A in the drawings represents a bottle or other vessel containing the liquid to be atomized.

B is the air-supply tube, which has a conical portion, 13, which is placed into the neck of the bottle A, and which is connected by a tube, Z), with an intermediate rubber bulb, O, which is provided with the usual valves for drawing in the air and forcing the same into the air-tube B. The bulb O is connected with an air suction and compressing bulb, D.

The intermediate air-bulb, 0, serves as a regulating reservoir by which a continuous supply of air to the air-tube is kept up, as is well known in atomizcrs of this class.

The nozzle E is inserted into the end of the air-supply tube B, preferably by accurately fitting the same, by means of a contracted portion, into the end of the air-tube B. To the inner end of the nozzle E is screwed or otherwise attached a suction-tube, F, which extends from the nozzle B through the airtube into the bottle A, the suction-tube terminating near the bottom of the latter.

The nozzle E is provided with a central longitudinal air-channel, e, that communicates with the suction'tube F and with one or more inclined air-channels, e, that communicate with the annular air-space in the air-supply tube 13 around the section-tube F, as shown in Fig. 2. The inclined channels 6 terminate in'the central channel, 6, so that the air forced in by the rubber bulb can act with full force on the liquid drawn up by the suction from the vessel A and discharged in the form of a fine spray of uniform density.

The described arrangement of the channels in my nozzle has the advantage that the nozzle produces always a reliable atomizing action Without any tedious adjustment of the same, as in the atomizer-nozzles heretofore in use. The simple insertion of the nozzle into the air-tube and its connection with the suction-tube is sufficient to produce the reliable action of the nozzle and the continuous spraying of the liquid contained in the vessel.

Another advantage of my nozzle is that the same can be readily removed for cleaning and replaced in position on the air-tube, as no screw-connection is required. Nozzles of different sizes may thus be used in connection With an atomizer for surgical or other purposes, and can be applied or removed with great facility and always remain uniform and effective in action.

Having thus described my invention, I claim as new and desire to secure byLetters Patent- A nozzle for atomizers provided with a central longitudinal channel, and one or more inclined air-channels communicating with said longitudinal channel, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.
